Try <Ctrl>+<End>.
This takes you to the bottom right corner of a box that surrounds all of the non-empty cells.
<Ctrl>+<Home> is the top left corner.
Alternatively you could try pressing <End>, then one of the arrow keys to move around. Bit difficult to explain, but it moves to the next cell in the direction you pressed, which is the start/end of a continuous block of non-empty cells in that row/column.
To compare different worksheets within the same file, you can cycle through them using <Ctrl> + <Page Up> (or <Page Down>)
Does this help?
